-myself and John Hoberg, Sr., for an adjustable reel for printingpresses.

One object of the present invention is to provide means whereby the internal gearing or other "mechanism for actuating the screw threaded radial arms of the reel, may be dispensed with, and said arms actuated more directly and from an exterior source.

A further object of my invention is to provide means whereby the use .of'holding devices which perforate the paper from the inner side may be dispensed with.

Another object ofmy invention is to provide a double set of reels, whereby one reel may be substituted for another without stopping the delivery of paper from a paper making machine.

In the drawings Figure 1 is a side elevation, showing a set of reels embodyingone phase of my invention. Fig. 2 is a.sec-. tional view drawn to a vertical'plan'eextending through the center of one of the reels shown in Fig. 1', the standards being shown in elevation. Fig. 3. is a side elevation of a reel, showing a modified form of contracting mechanism. Fig. 4 is a view of one end of a similar reel, shown in longitudinal section, illustrating a further modification of the paper gripping mechanism. Fig. 5 is a fragmentary view of the means for lifting and rotating. the paper holder.

Like parts are identified by the same reference numerals throughout the several views.

In Fig. 1,.a reel shaft 1 is journaled at each end in supporting arms 3, the latter being pivoted at 4 to a standard 5,whereby said arms 3 may be revolved to carry the reels bodily about the axis of the stud shafts 4; Thestud shafts 4 are at the centers of the, arms 3 with reel shafts 1 at each end. The. reel shafts 1 may be each provided withcylindrical gear boxes rotatably mounted thereon and from-whichextend sets of radial arms 10, which have swivel connection with the boxes, said arms being shown as-having bevel gear wheels 11 at their inner ends in mesh with a driving gear wheel 12. The arms 10 may therefore be rotated axially. Each of the armsis screw threaded; along its outer end" port on andadapteol to fit a threaded aperture: in a sleeve 13 on the peripheral reel bar 14, said bar being supported near each end by one of the radial arms, and there' being a sufli'cient number of these bars supported from the shaft by radial arms to support a strlp of paper which is being wound thereon. The outer surface of the bars:14 is preferably curved in an arc corresponding with the circle of revolution, and these surfaces may be considered as formng the periphery of the reel. The shaft 1 is relatively stationary but is rotated step bystep to contract'the reel. At one end therefore, it 'is'provided with a gear wheel 16. A star wheel 17 mounted to rotate on sleeve 13, strikes-a projection 18 once dur ingeach revolution of the sleeve and rotates a partial turn to permit the striking arm to pass such projection. This move ment is communicated to the shaft 1 through starfwheel pini'on 19 and gearwheels 16, the motion being also transmitted through bevel gear wheels 12' and 11 to the screw armslO, which are thus revolved in a series of step by step movements to cause the reel bars-14 to move inwardly. The pitch of the screw threads on thearms 10 is such that the reel bars will move inwardly a distance equalto the thickness of the paper which is being wound upon the reel. The roll of'paper, although-j constantly increasing in thickness, will thereforeremain of the same, diameter, the inner sheets buckling inwardly between the reel bars 14. The projection or striker 18 may be supported from any convenient point, such as the member 3-in which the trunnions 2 are journaled.

The specific meansfor actuating the radial arms or bars '10 isnot essential to the main-feature of my invention embodied in Figs. 1 and 2, and any means may be employed for this purpose. invention. relates more. particularly to the means for preventing the paper from rotat-,

In these views my;

ing on the reel. In Figs. land 2, I have illustrated the reel bars 14 as provided with ruptbend at 83,iadapted to cause an inward movement of the inner arm of the lever 26 to withdraw the blade from the recess 24 of the reel bar at that stage of the revolution of the reel during which the reel bar passes the point where the paper is being received;

As soon as the reel bar. with, the blades 25 pertaining thereto, passesthe paper receivingpoint, the roller 29 enters the'deeper portion of the cam groove 30, whereupon the inner end of the lever 26 will be drawn outwardly to force the blades 25 into the slots 24 to a point where they will slit the margins of the paper. It is not necessary that each of the reel bars 14 should be provided with a set of holding blades 25, but it is desirable that two of the reel bars should be provided with holding means whenever this type of holding means is employed, in order that one set of holding devices may be in operation during the period when the other set is retracted to pass the paper receiving point.

Referring to Figs. 3 and 4, it will be observed that the reel bars 14 .are each provided near their ends with peripheral apertures 40, into which holding pins 41 may be driven from the exterior, thus perforating the paper. The pins 41 are each supported by an arm 43 from a post 44, which is mounted for vertical movement in a bracket 45, carried by the reel. A fixed cam 46 supports the inner ends of the posts 44, and each post carries a coiled spring 48 which bears against the bracket 45 and presses the post 44 inwardly into contact with the cam faces. The cams are so formed that the pins 41 will engage the paper and project into the holes 40 at all stages of the revolution of the reel, except when passing the paper receiving point, at which period the cam will lift the post 44 to retract the pin 41. It is necessary that the pin 41 should not only be retracted radially, but that it should also beswung laterally toa point where itwill not strike the paper. This is accomplished by providing the post 44 with a screw thread'5O which, during the final outward movement of the post 44, en-

gages a projection or thread in the upper bearing of the bracket45, whereby during the final outward movement of the post 44,

said post will be rotated a partial turn to swing the arm 43 and pin 41 a partial turn to one side or the other. The screw thread 50 has sufiicient pitch to allow the post to move without great resistance when being thus rotated. The reel bars 14 are mounted upon and have threaded engagement with the radial arms 10, which arms are rotatably mounted in the brackets 45. Each radial arm 10 is provided with a star wheel 17 on its outer end which is adapted to engage a frame projection 18' Once during each revolution. 7

It is not essential to the operation of any of the holding devices herein described, that the specific actuating means herein shown be employed for contracting the reel, and so far as the holding mechanism is concerned, the contracting means shown and described in said former patent, or any other contracting means, may be utilized if desired, but the holding means illustrated herein are peculiarly adapted toruse in connection with.

the contracting means shown in Figs. 3 and 4, since both the holding means and the contracting means may, in this type of construction, be operated from the exterior, thus doing away with the necessity of employing a hollow shaft and mechanism within the reel for transmitting the contracting motion to the reel bars, and also doing away with the necessity of employing needles, such as are shown in said former patent, which perforate the paper from the inner side. If the holding means shown in Figs. 1 and 2 are used in connection with the contracting means shown in Figs. 3 and 4, the blades 25 will extend inwardlypast the radial arms at the respective ends of the reel, since in this construction the paper will be wound upon the reel wholly between the radial arms.

I claim 1. A contracting reel, comprising a central support, a series of radial arms having rotatable connection therewith, a set of reel bars carried by said radial arms, a motion receiving member mounted upon each radial arm exterior to the central support, and means for engaging and operating each motion receiving member once during each revolution of the reel, whereby said reel bars are adjusted together with means for holding a roll of paper against rotation when the same is being wound upon said reel bars, said holding means being adapted to move into and out of contact with the paper from a point exterior to the path of the paper in winding upon the reel.

2. In a contracting reel comprising a central support provided with rotative radial arms and peripheral reelbars carried thereby and movable radially when said radial arms are rotated, the combination. of a holdretracting said holding member once dur- Witnesses: ing each revolution of the reel While it E.
